[PATCH] scsi: core: Do not query the IO hints for a particular USB device

by Bart Van Assche

Recently it was reported that Kingston DataTraveler G2 USB devices are unusable with 6.9.x kernels. Hence this patch that skips reading the IO hints VPD page for these USB devices.

[PATCH v2 08/14] pinctrl: qcom: spmi-gpio: drop broken pm8008 support

by Johan Hovold

The SPMI GPIO driver assumes that the parent device is an SPMI device and accesses random data when backcasting the parent struct device pointer for non-SPMI devices. Fortunately this does not seem to cause any issues currently when the parent device is an I2C client like the PM8008, but this could change if the structures are reorganised (e.g. using structure randomisation). Notably the interrupt implementation is also broken for non-SPMI devices. Also note that the two GPIO pins on PM8008 are used for interrupts and reset so their practical use should be limited. Drop the broken GPIO support for PM8008 for now.

From 279428df888319bf68f2686934897301a250bb84 Mon Sep 17 00:00:00 2001 From: Marc Ferland <marc.ferland(a)sonatest.com> Date: Wed, 1 May 2024 11:05:54 -0400 Subject: iio: dac: ad5592r: fix temperature channel scaling value The scale value for the temperature channel is (assuming Vref=2.5 and the datasheet): 376.7897513 When calculating both val and val2 for the temperature scale we use (3767897513/25) and multiply it by Vref (here I assume 2500mV) to obtain: 2500 * (3767897513/25) ==> 376789751300 Finally we divide with remainder by 10^9 to get: val = 376 val2 = 789751300 However, we return IIO_VAL_INT_PLUS_MICRO (should have been NANO) as the scale type. So when converting the raw temperature value to the 'processed' temperature value we will get (assuming raw=810, offset=-753): processed = (raw + offset) * scale_val = (810 + -753) * 376 = 21432 processed += div((raw + offset) * scale_val2, 10^6) += div((810 + -753) * 789751300, 10^6) += 45015 ==> 66447 ==> 66.4 Celcius instead of the expected 21.5 Celsius. Fix this issue by changing IIO_VAL_INT_PLUS_MICRO to IIO_VAL_INT_PLUS_NANO.

[PATCH] ACPI: x86: Force StorageD3Enable on more products

by Mario Limonciello

A Rembrandt-based HP thin client is reported to have problems where the NVME disk isn't present after resume from s2idle. This is because the NVME disk wasn't put into D3 at suspend, and that happened because the StorageD3Enable _DSD was missing in the BIOS. As AMD's architecture requires that the NVME is in D3 for s2idle, adjust the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT advertises low power idle support. This will ensure that any future products with this BIOS deficiency don't need to be added to the allow list of overrides.
